The talus and calcaneus make up the two bones of the subtalar joint (STJ), otherwise known as the talo-calcaneal joint. The STJ consists of three articular facets, the posterior, middle and anterior facets. The two physiologic motions of the STJ are supination and pronation. During STJ supination, the talus glides posterior-superiorly on the posterior facet of the calcaneus. During STJ pronation, the talus glides anterior-inferiorly on the posterior facet of the calcaneus. The maximally pronated

Standing Subtalar Joint Axis Location Technique The axis of motion of the subtalar joint (STJ) should be of special interest to all podiatrists since the STJ axis spatial location relative to the plantar aspect of the foot largely determines the kinetics (i.e. forces and moments) of the STJ during weightbearing activities (Kirby KA: Subtalar joint axis location and rotational equilibrium theory of foot function. JAPMA, 91:465-488, 2001). The first technique described within the scientific litera

In this three dimensional animation of the dorsal aspect of the weightbearing foot skeleton during closed kinetic chain subtalar joint (STJ) motion, the STJ axis is noted to undergo adduction (i.e. internal rotation) relative to the ground with STJ pronation motion and abduction (i.e. external rotation) relative to the ground with STJ supination motion. Please note that the STJ axis has a relatively constant anterior exit point from the dorsal neck of the talus and a relatively constant exit poi
